    Re: need help to source part

    I think it's a 1.5uH choke but lets wait for a second opinion.
    .
    1R5 = 1.5
    L = Inductor

    The 1 in 1R5 looks like an I because of that dot over it but I think that dot is a lame attempt at a logo and the characters in the string are separate.

    Other string is a date code.

    Just my take.

      The identifier (PL10) on the circuit board would tend to say it's an inductor. I'm less confident in the interpretation of the number on it.

      Why do you feel it is bad?

          Have you checked it's continuity? Is the power supply working?

              This is probably used in a bucking power supply. If it were open or had shorted turns you would not have good voltages.

                And if it ain't broke you can measure it to find out what it is..

                  thanks for your replies i will give more info about the board.
                  i bought this in as a bios update that had failed the customer had bought
                  a battery with a software to flash the bios so the battery would work on this machine. There is 19v around the board but no life when you press the power button not even a led flash . surely this bios update would not cause this problem alone.

                    Try to boot to the BIOS with it on AC power with the battery removed and all the drives out.
                    If it has more than one memory module then try both but with only one installed at a time.

                        Check the 19 vdc on the board for AC voltage riding on the DC.
                        If you got some the power brick is defective.
